Subject: [PATCH 1/2] Add support for Blackfin

Taken upstream from
https://github.com/atgreen/libffi/commit/213ed15c70e72d666154c08e2b41dae3f61f20d3. Will
be part of the upcoming 3.0.12 release.

We have kept the part of the patches changing configure and
Makefile.in in order to avoid having to autoreconf the package, which
requires autoconf 2.68.

Code written by Alexandre Keunecke.
